Child Protective Services had a file open on Barnes in 2011 when police interviewed her 10-year-old adopted son. Court records previously obtained by New Times did not detail how police or CPS ended up interested in Barnes.

The boy told a forensic interviewer that Barnes would tie him up, shove dog feces in his mouth, and tape his mouth shut, according to the documents.

He said on other occasions, Barnes burned his penis with a lighter, and shoved his toothbrush into his anus.

The boy told the interviewer that Barnes made his penis bleed once, after burning it with a curling iron, then tying a necklace around it, according to the documents. He said these incidents all took place between May 2010 and August 2011.

A doctor examined the boy after the interview, and said there were scars on the boy's penis that were "consistent with healed burns," according to the documents. The doctor also saw scars on the boy's anus, which he noted were consisted with the abuse the boy described.

Barnes denied abusing the boy, but a Gilbert detective wrote in a probable-cause statement that she gave inconsistent information.

Barnes is scheduled to be sentenced on her two child-abuse charges on April 26.
